After a BA in Greek philology at the University of Athens, Dr Alexopoulou went to Edinburgh to obtain an MSc in Natural Language and Speech Processing and then a PhD in Linguistics. Before coming to Cambridge, she worked at the Universities of Edinburgh and York and held an Intra-European Marie Curie Fellowship at the University of Lille III, France.
Language Typology and Cognition, Second Language Acquisition, Corpus Linguistics
Dr Alexopoulou is interested in natural language syntax, as a manifestation of the human cognitive capacity for language, and in the way syntax shapes language learning. Her research looks at variation and diversity across languages and crosslinguistic influence in second language learning. One central question is how the similarity between a learner’s mother tongue and their second language influences the way they process and interpret it, how it impacts on their learning, even predicting proficiency scores in exams. Her practical goal is to develop learning methods and tools that can address learning challenges and improve outcomes. In this context she leads an research partnership with EF Education First as the PI of the EF Lab For Applied Language Learning. She approaches questions on language typology and cognition through Chomsky’s generative syntax and a combination of experimental and corpus data, in particular big data from online foreign language learning platforms.
Current research topics: language typology and cognition, L2 learnability, natural language processing for learner data, input processing instruction, child L2 acquisition, linguistic complexity in L2 development, crosslinguistic influence on semantic processing.
